Teams must submit their salary cap compliant final rosters by 5 p.m. Tuesday.

The Red Wings potentially have several forward spots that are fluid, as the final days of the preseason approach.

With restricted free agent Andreas Athanasiou still unsigned, and Tyler Bertuzzi (wrist) injured and unavailable for the next month, and the 13th (extra) forward probably up for grabs, the Red Wings could have two or three positions open.

Martin Frk increasingly looks as if he’s made the team, judging from coach Jeff Blashill’s comments Thursday, but players like veterans David Booth and PA Parenteau — both in camp on professional tryouts — and Luke Witkowski, and potentially Grand Rapids Griffins who can fill roles, all can make final impressions in the next few days.

“Right now, we’re looking to see how we can put our best team together,” Blashill said. “If those guys can make our team better, than they’re going to be on our team. There’s opportunity there, so let’s go out and grab it.”

Frk has pretty much gone and grabbed a spot alongside Dylan Larkin and Anthony Mantha, thanks to Athanasiou being out of camp.

“Marty Frk has done a good job of saying ‘I want to be that winger with Larkin and Mantha,’ ” Blashill said. “Frk has done a good job and he gets another chance to do it (Friday). Every time you’re on the ice, you get a chance to make a statement one way or another.
